ABSTRACT

A piggyback duffel apparatus and system provide a modular apparatus that expands a storage capacity of a backpack and includes a detachable piggyback duffel bag that may have a vertical strap to attach to loops on a side of the backpack.

BACKGROUND OF THE INVENTION

The present invention generally relates to bag and storage systems and apparatus, and more particularly to a piggyback duffel system and apparatus for providing an expanded storage capacity for a backpack.

Some devices for storing and carrying loads may not have readily expandable attachments or modular storage attachments that may be affixed to an outside surface of the device. Some other devices used for storing and carrying loads may not have separate compartments or spaces having specialized protection or weather proofing properties. Backpack design and manufacturing typically have a storage space contained by a single type or piece of material that may have a specific treatment or property that may determine the overall weather protection or weather proof property of the device. Still some other devices may not provide a plurality of specialized features or functionality that may be stored or attached on the outside of the device and easily deployed or detached therefrom.

As can be seen, there is a need for an improved system and apparatus that provides a modular attachment that may expand or add to the storage capability of a backpack and may provide different or improved weather resistant properties or specialized functionality.
